I just started to cool a cryostat with epics reading the temperatures and 
AR logging them.  I just happened to notice that the values written to 
disk were repititions of the initial temperatures, not what epics was 
currently reading, ie:

PROGRAM: AR
SAMPLE: at 10/24/95 10:39:16.020--operator snapshot
%endHeader%
ser3:ecalcs_54.VAL DBF_DOUBLE 0 0 1 8203.000
ser3:emosub_87.VALA DBF_DOUBLE 0 0 1 261.8000000
ser3:emosub_87.VALC DBF_DOUBLE 0 0 1 280.8000000
%endData%
PROGRAM: AR
SAMPLE: at 10/24/95 10:40:56.020--operator snapshot
%endHeader%
ser3:ecalcs_54.VAL DBF_DOUBLE 0 0 1 8303.000
ser3:emosub_87.VALA DBF_DOUBLE 0 0 1 261.8000000
ser3:emosub_87.VALC DBF_DOUBLE 0 0 1 280.8000000
%endData%

the temperatures are actually changing, I can see them on a dm display 
which is connected to exactly the same records/fields.

My archive script is:

NAME: ls1
DESC: test it
ACT: always
INACT: never
TRIGGER: every 0:1:40
SNAPSHOT: for 1 samples
OUTPUT: set:txt /net/idsun1/epics1/mch/epics/ar/arSet/ls2.txt
%endHeader%
ser3:ecalcs_54.VAL
F ser3:emosub_87.VALA
# F ser3:emosub_87.VALB
F ser3:emosub_87.VALC
F ser3:emosub_87.VALD
F ser3:emosub_87.VALF
F ser3:emosub_44.VALA

Dose anybody have any ideas?
